Method Description
Three replicate Van Veen grab samples (area 0.1115 m2) are obtained from respective observation location (FI_WELFIN_XLIV and FI_WELFIN_XXVI), sieved through 1 mm sieve and stored in 4 % formaldehyde solution until analysis in the lab. Animals are identified to the closest possible taxonomic level by morphology, and counted under the microscope. Animals are then weighed per taxa (blotted wet weight) and stored in 70 % EtOH.
